26650 3600mah lithium iron battery cell for high-drain devices/flashlights


About 26650 lithium phosphate battery cell.

  • 26650 lithium ion battery is with lifepo4 as positive electrode,the size 26*65mm high.26650 can be battery pack,prismatic cell for many applications,such as solar storage,LED street lamp,enerfy back up,RV,home energy system,E-car,bicycle etc.
  • Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive/negative electrode material and uses a non-aqueous electrolyte solution.
  • Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.

  • Deligreen's 18650 supplies good quality and real 1500mah capacity.

  • All 26650 we supply is grade A.

Lithium battery is the trend to replace the lead acid battery.

Standard Charge

(The "Standard Charge" means charging with constant current 0.2C 5 to3.65V, then charging with constant voltage 3.65V to 0.01C 5 under 20±5 , ℃ charging time will not more than 8h.) (Use Lithium-ion battery charger, which

with an accuracy ±0.05V.)


Nominal Capacity

The capacity means the discharge capacity of the cell, which is measured with discharge current 0.2C 5 to cut-off voltage at 2.0V at 20±5℃ rest for 30minutes after the Standard Charge.

Nominal Capacity

≥3600mAh


Cycle Life

After 2000 cycles of charge and discharge, the discharge capacity is measured

with 0.2 C5A discharge current and 2.0V cut-off voltage.


≥80%Nominal Capacity


Storage

Test the cell initial capacity using 0.2C 5 current at 23±2℃ and record,then charge the cells with 45% capacity, then storage for 3, 6, 12 months respectively at 20±5℃and relative humidity of 45%~75%, then the cell is cycled for 5 times with charge with 0.2C 5and discharge with 0.2C 5 at 23±2℃, The maximum discharge capacity

(longest discharge time) is recorded.

0.2Cdischarge time:

After 3 months storage ≥4.5hrs; After 6 months storage ≥4.25hrs; After 12 months

storage ≥4.0hrs)

The cell is charged and discharged using 0.2C 5 at 20±5℃. The dischargeCapacity Retention
capacity is C1. The cell is stored for 28 days in 20 ±5℃ after fully charged andC2/C1≥90%
then is discharged using 0.2C 5 at 20±5℃. The capacity is defined as C2.

After the test as C 2 , The cell is charged and discharged using 0.2C 5 at 20± 5℃, The discharge capacity is C3.
